Guide to Using Harris Parts List Information

The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index. The

example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of materials

table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the Replaceable

Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level below the

Transmitter and implies that they are used in the Transmitter. The Controller Board is indented one level below the

Control Cabinet so it will show up in the bill of material for the Control Cabinet. The tree structure of this same index is

shown to the right of the table and shows indentation level versus tree structure level.

Example of Replaceable Parts List Index and equivalent tree structure:

Replaceable Parts List Index Part Number Page

Table 7-1. Transmitter 994 9283 001 7-2

Table 7-2. Control Cabinet 992 9244 002 7-3

Table 7-3. Controller Board 992 8344 002 7-6

Table 7-4. PA Cabinet 992 9400 002 7-7

Table 7-5. PA Amplifier 994 7894 002 7-9

Table 7-6. PA Amplifier Board 992 7904 002 7-10

Table 7-7. Output Cabinet 992 9450 001 7-12

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that part

number starts. Inside the actual tables, four main headings are used:

•Table #-#. ITEM NAME - HARRIS PART NUMBER - this line gives the information that corresponds to the

•Replaceable Parts List Index entry;

•HARRIS P/N column gives the ten digit Harris part number (usually in ascending order);

•DESCRIPTION column gives a 25 character or less description of the part number;

•REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102,

etc.) that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the

schematic) or 2) gives added information or further explanation (i.e., “Used for 208V operation only,” or “Used

for HT 10LS only,” etc.).

Inside the individual tables some standard conventions are used:

•A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column

means that this item is used on or with C001 and is not the actual part number for C001.

•In the ten digit part numbers, if the last three numbers are 000, the item is a part that Harris has purchased and has

not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured by

Harris or is purchased from a vendor and modified for use in the Harris product.

•The first three digits of the ten digit part number tell which family the part number belongs to - for example, all

electrolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found

to have a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been

modified in some manner at the Harris factory and will therefore show up farther down into the individual parts

list (because each table is normally sorted in ascending order). Most Harris made or modified assemblies will

have 9xx xxxx xxx numbers associated with them.

The term “SEE HIGHER LEVEL BILL” in the description column implies that the reference designated part number will

show up in a bill that is higher in the tree structure. This is often the case for components that may be

frequency determinant or voltage determinant and are called out in a higher level bill structure that is more

customer dependent than the bill at a lower level.

1.2 Ranger Transmitter Models

The Ranger Series™ transmitter utilizing FLOTM technology is available in 2 power levels as

listed in Table 1-1.Both systems are designed to use external (low loss) mask filters for maximum

usable RF power output.

The Ranger control system is adapted from the state-of-the-art Atlas Series UHF solid state

transmitter using a very simple control panel and easy to use Graphical User Interface or GUI.

It consists of a single cabinet with an Apex exciter, a single power supply and one or two PA

modules depending on the model.

Figure 1-1 at right, shows a front view of the Ranger transmitter. All Ranger models look identical

due to the use of false module covers for the 2 or 3 right-hand slots.

1.4 Transmitter Control System

The transmitter uses a distributed architecture control system. This means that each transmitter

sub-system is responsible for its own monitoring and protection and simply reports back to the

Main Controller for display on the GUI (Graphical User Interface) or to a remote interface. The

heart of the system is the 376 Micro Module which is used in all of the transmitter systems for

control, monitoring and protection. The Micro Module is used on each of the following

controllers and sub-systems:

a. Main Controller Board - This board is responsible for transmitter control and

monitoring. However, with the distributed control architecture, it is not directly

responsible for protection of the individual transmitter components. It merely

gathers all status and fault data from the individual sub-systems and reports that

information to the operator. The Main Controller is responsible for system level

control (issues which effect multiple systems) since it is the only part of the con-

trol system which can monitor the entire transmitter.

b. RF Monitor Board - Responsible for cabinet VSWR protection and monitoring of

combiner reject loads. Reports directly to the Main Controller.

c. Power Supply Monitor Board - Responsible for control and monitoring of the PA

power supply and distribution of the low voltage. Also responsible for monitoring

the cooling system including temperature and air pressure. Reports directly to the

Main Controller.

d. External I/O Board - Provides all customer interface connections including paral-

lel remote control. Reports directly to the Main Controller.

e. PA Module Controllers (1 in each module) - This is not actually a 376 micro

module but is a micro controller and is responsible for protection and control of

the PA Module. Reports directly to the Main Controller Board via the CAN bus.

1.4.1 Graphical User Interface

The front panel user interface is a 1/4 VGA, LCD touchscreen display. The touchscreen display is

used to monitor the transmitter. Hardware buttons for the primary transmitter functions such as

ON, OFF, RAISE and LOWER are provided on the overlay panel next to the display.

1.4.2 Control System Communications

The control system uses a serial communications system called a CAN bus. CAN stands for

Controller Area Network. The CAN bus is a closed loop serial network operated by the Main

Controller Board. Each circuit board and module connected to the CAN bus is considered a node

and therefore has a specific address. This allows the Main Controller to gather information from

all parts of the transmitter and display it on the GUI. One big advantage of the CAN bus is that it

1-6 888-2685-001 12/24/07

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction Ranger Commissioning Manual

requires only 2 wires of the system control ribbon cable, eliminating a large amount of discrete

wiring which would otherwise be required.

For redundancy, the CAN bus is backed up by parallel, hardwired, control lines that allow the

transmitter to stay on the air even if the CAN bus fails. The parallel control lines also provide the

instantaneous OFF and RF MUTE commands necessary for transmitter protection.

1.4.3 In-System Programming or ISP

The use of the CAN bus for communication between the various Micro Modules in the transmitter

also allows for easy updating of the software used in each transmitter sub-system via a serial port

connection to an external computer. This is referred to as In-System Programming or ISP.

The real benefit of In-System Programming is that it allows any or all of the transmitter software

to be updated without removing or replacing any firmware ICs. The Harris ISP program is

provided on the CD-ROM accompanying this manual along with all of the transmitter software as

it shipped from the factory. The Harris ISP program is easy to use and it only takes a few minutes

to load or update software.

NOTE:

Software does not need to be loaded into the transmitter unless new components

are installed or an update is sent from Harris. The transmitter, as shipped from the

factory, is preloaded and ready to run.

1.4.4 Remote Control

The Ranger Series™ transmitter has all of the standard parallel remote control, status and analog

metering connections for use with a third party remote control system. For a complete listing of

the remote control connections, see Table 2-1, Table 2-2 and Table 2-3 at the end of section 2.

1.5 PA Module

The Ranger Series™ PA Module utilizes the same LDMOS amplifier module as used in the

Diamond Series DTV transmitter. Each PA Module will produce up to 400W average power

output. A block diagram of the PA module is shown in Figure 1-3.

12/24/07 888-2685-001 1-7

WARNING: Disconnect primary power prior to servicing.

Section 1 Introduction

Ranger Commissioning Manual

Figure 1-3 PA Module Block Diagram

Each PA module consists of the following components:

a. PA Module Controller Board - Responsible for all monitoring and protection of

the module. Reports to the transmitter Main Controller via the CAN bus but is

also connected to the parallel control lines in case the CAN bus is not operational.

Also provides for FET switching and distribution of the +32Vdc power to the

driver and PA pallets and sensing of driver and pallet currents.

b. Phase and Gain Board - Provides for module phase and gain adjustments to mini-

mize the PA module combiner reject power for the CZ1000F.

c. One LDMOS Driver Pallet - Provides enough power to drive the 6 way splitter

and the inputs to the power amplifier pallets.

d. Six-way Pallet Splitter and Combiner.

e. Six (6) LDMOS Amplifier Pallets - When combined, they provide up to 400

watts of average power at the output of the module. These pallets are field

replaceable.

f. RF Output Directional Coupler - Samples both Forward and Reflected power for

metering, module ALC and module VSWR protection.

Section 1 Introduction Ranger Commissioning Manual

Each Ranger Series™ PA Module is a self-contained transmitter (except for the power supply)

with its own internal control, monitoring and protection. The modules only receive basic On/Off,

Mute, Restart, Phase and Gain commands from the transmitter control system. This means that

each module will protect itself without relying on the system controller.

1.6 Power Supplies

A single +32 Vdc switching power supply is used to provide the DC voltage to the PA modules

within each PA cabinet. The power supply can provide power for 1 or 2 PA modules. The control

system in the PA Cabinet is powered by a self contained low voltage power supply with +/-15Vdc

and +7.5Vdc outputs.

1.7 Apex™ Exciter

For information on setup and operation of the Apex Exciter utilizing FLOR technologies refer to

the separate exciter manual, 888-2604-001. The exciter manual is bundled with the transmitter

documentation for shipment.

2.6 Signal and Ground Connections

NOTE:

Control and signal wires should never be run in the same conduit with any AC

wiring. A separate conduit should be used for control/signal cables.

Confirm that the ASI input is connected to

the terminal (may be labeled SMPTE 310M

as seen in the photo). There are 2 bulkhead

BNC connectors located just inside the back

door at the top of the cabinet as shown to the

right.

NOTE:

Note that the 10Mhz reference is

optional.

Verify that a ground strap is connected from the transmitter cabinet to the station

ground. There is a brass ground block located on top of the cabinet or a strap coming

out the back of the cabinet (only one should be used). For connection to the top of the

cabinet, remove the block, punch holes in the copper ground strap and then mount the

strap under the block. The loose strap at the bottom of the cabinet should be soldered to

the station ground strap. The copper strap must be at least 2" wide.

2.7 Interlock Connections

There are 2 types of interlock connections for the Ranger:

• External Interlock which shuts the transmitter off and requires the user to

give an ON command (local or remote) to turn the transmitter back on. Used

for protection of personnel and equipment. For more information see "2.7.1

External Interlocks" on page 2-8.

• RF Mute Interlock which only mutes the rf drive and therefore reduces the

transmitter power output to zero. This interlock is meant to be used for a

motorized RF switch or possibly a dummy load thermal interlock.

NOTE:

To operate the transmitter without any interlock connections requires 3 jumpers:

• J18-1 to J18-8 (defeats the External Interlocks)

• J18-9 to J18-12 (defeats the RF Mute Interlocks)

• J14-1 to J14-3 (defeats the RF Switch Status feedback interlock)

2-8 888-2685-001 12/24/07

WARNING: Disconnect primary power prior to servicing.

Section 2 Installation Verification & Ranger Commissioning Manual

2.7.1 External Interlocks

The transmitter has inputs for up to four

external interlocks on the External I/O

Board. Note that these 4 connections

comprise one interlock with 4 series

connection points. The transmitter, as

shipped from the factory, has no external

interlock connections. The Ranger External

I/O Connection schematic (843-5560-105 or

843-5549-141, sht 20) shows that Interlock

#1, J18-1 to J18-2, is usually used by a 3

port patch panel. The other three are to be

used at the customers discretion.

IMPORTANT:

The External Interlock circuit requires a closed connection between all of the fol-

lowing terminals on the External I/O Bd to turn the transmitter on:

• J18 pins 1-2 (usually connected to 3 port patch panel)

• J18 pins 3-4 (for customer use)

• J18 pins 5-6 (for customer use)

• J18 pins 7-8 (for customer use)

2.7.2 RF Mute Interlock

There are 2 more interlock connections on J18 which can be used to apply an RF Mute;

instead of a Fault OFF condition as discussed above. This could be used for RF switch

changeover or a dummy load thermal interlock. The connections are:

•J18-9 to J18-10

•J18-11 to J18-12

! CAUTION:

THE RF MUTE INTERLOCK CONNECTIONS ARE NOT TO BE USED IN ANY

SITUATION WHERE PROTECTION OF PERSONNEL IS AN ISSUE

2.8 3 Port Patch Panel Connection Confirmation

IMPORTANT:

If no patch panel or motorized switch is to be installed in the transmitter RF out-

put line, or if the patch panel does not have status switches, then a jumper must

be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1

(ground).

NOTE:

Refer to the Ranger External I/O Connections schematic 843-5560-105 for the

following connections: (S1 = Antenna position / S2 = Test Load position)

Connect one side of S1A and S2A on the patch panel to J18-1 and the other side to

J18-2 on the External I/O Board in the transmitter. See External I/O Schematic 843-

5549-141, sheet 20, for External interlock connections. This is the transmitter external

interlock input and will shut the transmitter off if the U-Link is removed during

operation. A closed contact between J18-1 and J18-2 is required for the transmitter to

operate. Jumpers must also be placed in the other 3 External Interlock positions, J18-3

to J18-4, J18-5 to J18-6 and J18-7 to J18-8 or one jumper from J18-3 to J18-8.

! CAUTION:

ALWAYS SHUT THE TRANSMITTER OFF BEFORE REMOVING THE U-LINK

TO PREVENT POSSIBLE DAMAGE TO THE CONTACTS.

If the RF Mute interlock connections are not going to be used (and they are

normally not used for patch panels), connect a jumper from J18-9 to J18-12.

If the patch panel has status switches then connect S1B and S2B to the RF switch

status inputs on J14 of the External I/O Board in the transmitter. This allows the

GUI to display the position of the patch panel and will cause a transmitter mute if

neither of these connections are pulled low. These connections include:

• S1B and S2B commons connect to J14-1 (ground)

• S1B (antenna position) connects to J14-3

• S2B (test load position) connects to J14-4

NOTE:

If the patch panel does not have status switches then a jumper must be placed

between J14-1 (ground) and J14-3 (RF_SW_A_STAT) on the External I/O board.

The transmitter will be muted without this connection.

Section 2 Installation Verification & Ranger Commissioning Manual

2.9 Motorized RF Switch Connections (if equipped)

IMPORTANT:

If no patch panel or motorized RF switch is to be installed in the transmitter RF

output line, or if the RF switch does not have status switches, then a jumper must

be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1

(ground).

NOTE:

Refer to the Ranger External I/O Connections schematic 843-5560-105 for the

following connections: (S1 = Antenna position / S2 = Test Load position)

The RF_SW_SEL_OUT at J15-9 on the External I/O board is connected to the

select input on the switch. This output is a TTL open collector, active low, momentary

signal meant to cause a switch to the opposite position. The RF switch should then latch

in that position until pulsed again.

One side of S1A and S2A (interlock switches on the rf switch) is connected to J18-9

and the other side to J18-10 on the External I/O Board in the transmitter. See

diagram 843-5560-105 and/or 843-5549-141 sheet 20, for RF Mute interlock

connections. This is one of the transmitter rf mute interlock inputs and will mute the

transmitter while the switch changes position. Another jumper must be connected

between J18-11 & J18-12 to operate the transmitter.

If the patch panel has status switches then S1B and S2B are connected to the RF

switch status inputs on J14 of the External I/O Board in the transmitter. This

allows the GUI to display the position of the patch panel and will cause a transmitter

2.11 Initial Turn-On

Read and understand the entire initial turn-on procedure before starting. Detailed use of

all GUI screens is given in Section 3 Operation/Alignments.

Shut off the control circuit breaker CB1 and the PS Module breaker (both located

on the bottom front of the transmitter).

Apply primary power to the transmitter at the ac mains disconnect. Be ready to

quickly disconnect the power if necessary.

Turn on the Control circuit breaker, CB1. This should power up the LVPS and bring

up the GUI display. It may be necessary to turn on the LVPS switch (letter “C” in Figure

2-1 on page 2-2). It is located in the back of the transmitter at the top of the controller

assembly.

The GUI display should show the Home (default) screen shown in Figure 2-4. Try using

the touchscreen buttons on the right side of the GUI display (not the hardware buttons

to the right of the GUI). If they do not seem to be working or only work when pressed

outside the button graphic, then go to “5.7 Touch Screen Calibration” on page 3-20

before continuing. If the buttons are working then proceed on to the next step.

2.11.1.1 Verify Exciter Signal Connections

Most of the input and output connections are at the rear of the exciter, only the RS232

connections are available at the front and rear. Figure 2-9 shows the rear panel

connections.

Figure 2-9 Exciter Inputs and Outputs

ASI #1 and or ASI #2 are connected to the exciter for the low and high priority ASI

transport streams. For best common mode rejection, this cable shield should be

grounded only at the source end.

The input impedance for each connector is 75 ohms. Belden 8281 or similar high-

quality video cable can be used to deliver this signal to the exciter over a distance of up

to 1000 feet.

ASI OUT is a sample output of the active transport stream. It should not have a cable

connected to it unless specified locally.

ANT (GPS antenna input) connector should not have a cable attached since the GPS

receiver is an option and not present in most Mobile exciters.

10MHZ REF IN (BNC) is optional and normally not used in a Mobile system.

1PPS (1 pulse per second input from the GPS receiver) should have a cable connected

to it that comes from the GPS receiver.

HPF RF SAMPLE IN (SMA) has a cable connected to it that comes from the output of

high power mask filter. It is used by RTAC™ (Real Time Adaptive Correction) to

correct for the linear distortions of the high power filter. Normal input signal range is -

30 dBm to 0 dBm. The input impedance is 50 ohms.

PA SAMPLE IN (SMA) should have a cable connected to it that comes from the output

of the transmitter power amplifier, taken before the HPF and after the PA combiner for

transmitters with multiple PAs. It is used by RTAC™ to correct for the nonlinear

distortion caused by the power amplifier. Normal input signal range is -30 dBm to 0

dBm. The input impedance is 50 ohms.

IPA SAMPLE IN (SMA), is not used. There should be no cable connected to this

exciter input.

RF OUT (SMA) should be have a cable connected to it. This is the on-channel RF

signal output from the exciter. The output level is adjustable up to 250 mW average but

is intially adjusted to produce an 80 ALC value on the transmitter GUI display.

EXC/CTRL UHF (25 Pin D) should not have a cable connected to it.

CAN (controller area network) should have a cable connected to it. The connector is a

provision for the exciter to communicate with the transmitter GUI (graphical user

interface) system controller.

LAN 10Base-T should have a cable connected to it. The connector is a provision for

connecting the exciter to a local area network.

RS232 (on front and rear panels of exciter) is a 9 Pin D interface connector and they

should not have cables attached to them. They are used to communicate with various

computer applications. The front and rear panel connections can be programmed and

used independently of each other.

2.11.1.2 AC Power

AC Power is applied through a standard power cord to the connector at the right side of

the rear panel as shown in Figure 2-9. The AC inlet connector also contains the power

switch.

The power supply will automatically select the AC input voltage in two ranges. The two

ranges are 85 to 132 VAC or 170 to 264 VAC

2.11.1.3 Verify Installation of the GPS 1PPS Signal

The GPS (global positioning system) 1PPS (1 pulse per second) signal has a rise time in

the order of a few nanoseconds. It is delivered by a 50 ohm transmission line to the

exciter. Improper termination can cause ringing on the pulse, which, if severe enough

can cause timing errors in the system. The 1PPS signal must be properly distributed and

terminated to avoid the ringing problem.

2.11.2 RF Initial Turn ON

Shut the transmitter OFF. The transmitter should be initially powered into a test load.

Measure the test load impedance prior to application of RF power. The load can be

measured with a network analyzer prior to application of RF. Typical load VSWR

values are < 1.05:1 at the operating channel. If verification of load VSWR is not

possible then proceed with RF turn on at low levels and gradually increase power while

monitoring reflected power levels. If significant reflected power levels are noted then

measurement of the test load will be required.

Set the Exciter power to zero. This can be done using the lower button on the exciter

GUI or the Lower button on the transmitter control panel.

Switch ON the ac breaker on the front of the PA power supply. Monitor the Power

Supply screen shown in Figure 2-5 on page 2-13.

Press the transmitter ON button. Make sure the PA PS reading is close to 32Vdc.

Next, go to the Power Amp screen shown in Figure 2-12.

calibrated as part of the factory testing. If the calibration is not correct as determined by

a digital power meter, refer to "3.7.3 Forward and Reflected Power Calibrations" on

page 3-20.

Slowly bring up the transmitter power to the nominal value, as indicated by the

bar graph. Monitor the cabinet forward and reflected powers, as well as the VSWR

reading. A large VSWR (above 1.1) is indicative of a bad RF connection to the test

load.

Check the PA Module “Gain Balance” on the PA Setup screen (press Power Amp,

PA Service, PA Setup to get to Figure 2-14). This is adjusted at the factory and does not

require re-adjustment as long as the current readings in Figure 2-14 are within 1 amp of

3.1 Introduction

This section gives detailed operation and adjustment information for the Ranger™

Series Solid-State UHF Series transmitter. It contains all information necessary to make

any operational changes or adjustments which appears on any of the Graphical User

interface (GUI) Touchscreen display screens.

NOTE:

Operation and adjustment of the Apex exciter using FLOR Technology is covered

in a separate manual which came with the transmitter.

3.2 Transmitter Control Panel

The front panel user interface is a 1/4 VGA, LCD touchscreen display. The touchscreen

display uses software buttons to monitor the transmitter. Hardware buttons for the

primary transmitter functions such as ON/OFF, RAISE/LOWER and Remote Enable/

Disable are provided on the overlay panel next to the display as shown in Figure 3-1.

Section 3 Operation and Adjustments

3.2.1 Main Menu “Hardware” Buttons

Just to the right of the touchscreen, there are 5 hardware

buttons which are part of the front panel overlay.

Located next to each button is a Status LED which

illuminates green under normal, no fault conditions.

These buttons provide quick access to each of the 5

main transmitter groups, namely:

a. Drive Chain

b. Power Amp

c. Output

d. Power Supply

e. System

The Status LED next to the button will turn red if there

is a warning or fault condition in that section of the

transmitter. It will be green if the sub-system is normal.

This provides quick access to the required and relevant

diagnostics information, without having to be familiar

with a menu structure.

NOTE:

To differentiate these buttons from the ones which show up on the LCD display,

these will be referred to as “Hardware” buttons in the manual text.

3.3 Graphical User Interface (GUI)

The GUI (“Gooey”) was designed to provide an intuitive interface into the transmitter

control system. Once you know what information is available, finding the information

you want is simply a matter of following the screens to the desired section of the

transmitter. Menu Trees of all available screens is given at the end of this section, see

"3.10 GUI Menu Structures" on page 3-32.

For the most part, all navigation through the GUI screens is done via the touchscreen

and softkeys (software buttons). The exceptions are the 5 hardware buttons mentioned

above. The touchscreen display is also divided into an active display area, which will

change with each screen, and the global areas which are present on all screens.

The second line of the display has operational and status information including:

a. ON, Standby, OFF or Fault OFF as well as status information.

b. Transmitter Forward power output reading (after Filter) in numerical format.

c. Transmitter Forward power output reading in a Bargraph format. The 100% mark

is based on the nominal power level or TPO (Transmitter Power Output) entered

into the System Setup screen in Figure 3-22. The bargraph will also turn yellow if

the power level is more than 20% higher or lower than the nominal 100% level.

d. Main Menu Symbols which are basically status for the 5

main transmitter sections. If illuminated red, as shown to

the right, that section of the transmitter has one or more

faults. These status indicators correspond to the 5 hardware

buttons to the right of the display.

The icons on the top bar in Figure 3-2 should be all green under

normal (no fault) operating conditions. A red symbol or status

3.6.1.1 Module 3 strike Routine

Under certain critical fault conditions, the PA module will try to shut off (Strike) and

then re-initialize to try and clear the fault condition. If the fault is still present after the

module turns back on it will shut off (Strike) again. If the fault is still present after a 3rd

strike or returns within several seconds after the 3rd strike, the fault is latched and the

module is shut off. The module may be turned on again by pressing the transmitter ON

button. If the fault is still present, the module will simply repeat the 3 strike routine

again. Table 3-1 tells which faults activate the 3 strike routine.

3.6.3 PA Data

The PA Data screen in Figure 3-9 is accessed from the PA Meters screen in Figure 3-8.

It contains vital information about the operation of the PA module. The readings are

ADC or DAC counts in either 10 bit (0 - 1023) or 12 bit (0 - 4095). For detailed theory

on the PA Module refer to Section 4, Theory of Operation.

a. Phase - This is an analog voltage from the Backplane Interface board which is

used to adjust the insertion phase of the module. In the CZ1000F this is used to

adjust the phase of PA Module 2 to match that of PA Module 1 (and to optimize

the PA Module combiner). The module controller converts the analog voltage

from the Backplane Interface board to a digital 10 bit word from 1 - 1023 with the

ideal being 512 or centered in the range. PA Module 1 receives a fixed voltage

which places it approximately in the center of the range (it is not critical), while

module 2 receives a variable voltage via R7 on the Backplane Interface to allow

for module phasing. This input controls the I and Q Vector outputs to the Phase

and Gain board in the module.

Figure 3-9 PA Data Screen

b. I and Q Vectors -These are 12 bit DAC outputs from the module controller to the

Phase and Gain board in the module with a range of 0 - 4095. The phase voltage

from the Backplane Interface board adjusts these readings in opposite directions

to set the insertion phase through the module but they are also used to adjust the

module gain as part of the module AGC. These readings are considered OK as

long as they are not at the limit of the range. If either of these numbers are 0 or

4095, the PA Faults screen will register an AGC Unlock fault.

c. Phase Preset - This is a fixed setting inside the module and should read approxi-

mately 512.

WARNING: Disconnect primary power prior to servicing.

Ranger Commissioning Manual

Section 3 Operation and Adjustments

d. DAC Counts - These are 10 bit (0-1023) ADC samples of the detected RF input

and Forward and Reflected power output.

• IN - Is a sample of the detected RF drive input to the module. Nominal input

for 400W output is 15mW. This number is usually in the 800 range for full

rated output. The input overdrive fault is detected from this reading and is

triggered when the DAC reading is approximately 1.9dB above nominal or

• Out - This is a sample of the detected forward power sample from the

directional coupler on the module output. This is used for metering and as

the sample for the module AGC. This number is forced by the AGC to track

the IN reading, thereby keeping the module gain at 46dB.

• Reflected - This is the detected sample from the reflected coupler on the

module output. It is used for metering of reflected power or VSWR. Can be

used as a relative reading to detected changes in the module output.

e. Module Settings - These are status readings from the module to the transmitter

controller. The FREQUENCY and the BAND are set via the Channel number

entered into the System Setup screen shown in Figure 3-22. These are simply

read backs to verify that the module is setup properly. If not set properly, module

calibration could be affected. All Ranger modules should read HD (High power

Diamond) under TYPE.

The Bands are:

• Band A/B - Channels 14 - 41

• Band C/D - Channels 42 - 69

3.6.4.1 PA Setup (Gain Balance)

This screen is accessed by pressing the PA Setup button in Figure 3-10. Its sole purpose

is to balance the gain of the 2 PA modules in the CZ1000F transmitter. The goal is to

match the 2 module gain readings. Adjustment is only required if the module current

readings in Figure 3-11 are more than 1 amp apart. This procedure will have to be done

if a module is changed. The adjustment procedure is simple.

NOTE:

This adjustment should only be done at full power and after the module tempera-

tures have had time to stabilize. PA Module phasing should always be optimized

after finishing this procedure.

STEP 1 Press the RESET button. This allows the adjustment to always start from

a common point.

STEP 2 Use the Left and/or Right arrow buttons until the numbers match. There

will be some bounce in the readings, but they should be as close as

possible and no more than 1 amp apart.

3.7.1 Output Service

This screen is accessed from the Output screen in Figure 3-12. It is used for 2 purposes:

a. To monitor the PA Module Circulator reject power. Provides a bargraph and a

DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being maxi-

mum). This allows for a relative reading which can be monitored for changes

which could mean increased system VSWR or a bad circulator. There is no

adjustment for this reading.

b. To monitor Combiner Reject Load Power in the CZ1000F. Provides a bargraph

and a DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being max-

imum). It is used to adjust the phase relationship of PA Module #2 to minimize

the power to the module combiner reject load. The combiner reject load is actu-

ally a 40dB 1kW attenuator whose output is sent to the RF Monitor board where

it is detected and then A/D converted for the reading shown below the “PA 1&2”

bargraph. It is a relative reading which will simply be minimized with the phasing

adjustment R7 on the Backplane Interface board. See "3.7.2 Module Phasing Pro-

cedure".

NOTE:

The GAIN button can be toggled between LOW and HIGH, with high only being

3.7.2 Module Phasing Procedure

NOTE:

This procedure is for the CZ1000F only.

The goal is to minimize the PA module combiner reject load power reading in Figure 3-

13, by adjusting the phase of module #2. The phase of PA module #1 is fixed. The “PA

1&2” reading should be less than 0030 with the GAIN button at the bottom of the

screen set to LOW. If the GAIN button is pressed it will toggle to high, increasing the

detector gain and allowing for finer resolution when adjusting module phasing. The

reading should be less than 0100 with the GAIN set to HIGH.

STEP 1 Check the PA module gain balance on the PA Setup screen, shown in

Figure 3-11 on page 3-14. These current readings should be less than 1

amp apart. If not, refer to "3.6.4.1 PA Setup (Gain Balance)" and adjust

the module gains before proceeding with the module phasing.

STEP 2 Using a digital voltmeter, monitor the test point on the Backplane

Interface board shown in Figure 3-14.

Figure 3-14 Test Point for Module Phasing

STEP 3 Adjust R7 (the only potentiometer) on the Backplane Interface board for

minimum voltage reading on the voltmeter. This should minimize the

reading on the Output Service screen in Figure 3-13. The location of the

Backplane Interface board is shown in Figure 2-1 on page 2-2 under the

letter N.

NOTE:

The reject power should be less than 12W when finished.

3.7.2.1 Output Setup

This screen is accessed by pressing the Output Setup button on the Output Service

screen in Figure 3-13. It is used to calibrate the filter input power and Total cabinet

Forward and Reflected power (after the filter).

It also calculates the VWSR protection thresholds of Foldback power and Fault

threshold and displays them at the bottom of the screen. These values are based on the

“Nominal Power Output” value entered into the System Setup screen in Figure 3-22 on

page 3-27.

• The foldback level is calculated using a VSWR = 1.4:1. Therefore the actual

foldback power can be calculated as:

Foldback Power = Nominal Power Output x 0.0278

• The fault threshold is calculated using a VSWR = 1.9:1. Therefore the actual

fault threshold can be calculated as:

VSWR Fault Threshold = Nominal Power Output x 0.0963

3.7.3 Forward and Reflected Power Calibrations

The following procedure is used to calibrate the forward and reflected power readings

via the Output Setup screen. The forward must be calibrated first, then the reflected can

be calibrated. The procedure requires a digital power meter and a 10dB pad. Since

calibration is relatively easy and quick, it is recommended that both forward and

reflected always be calibrated together.

Forward Power

STEP 1 Connect the digital power meter to the forward power (incident) port on

the directional coupler either before or after the filter. For the location of

these ports see Figure 2-1 on page 2-2, designated B and R. The cables

numbers connected to these ports are #40 for the Total output and #42 at

the filter input.

STEP 2 Measure the power at the forward coupler. The coupler comes with a

table of precision coupling values for the various UHF channels which

should be used as the offset for the digital power meter. Make sure the

coupler serial number matches the coupling table. The coupling values

are also written on stickers which are attached to the couplers at the

factory.

STEP 3 Press the CHANGE button to select the coupler being calibrated (before

or after the filter) and then use the +/- buttons to make the displayed

power match the measured value on the digital power meter.

STEP 4 Press SAVE to store the setting or CANCEL to discard the changes.

Reflected Power

STEP 5 Press the CHANGE button for the desired reflected coupler (before or

after the filter). This temporarily disables the reflected power fault.

STEP 6 Note the forward power and remove the power meter from the forward

coupler. Connect the 10dB pad to the forward power coupler.

STEP 7 Remove the cable from the reflected coupler to be calibrated and connect

it to the 10dB pad. The cables are labeled #50 for the Filter input and

#39 for the Total reflected.

STEP 8 Use the +/- buttons to set the reflected reading on the GUI to 10% of the

forward reading noted earlier.

STEP 9 Press SAVE to store the setting or CANCEL to discard the changes.

3.8 Power Supply Main Menu

If you press the Power Supply button on the control panel

overlay, it will take you to the screen shown in Figure 3-

16. The Power Supply Menu Tree is shown in Figure 3-32

on page 3-33.

This is the overall Power Supply metering screen for both the PA Power Supply, the

Low Voltage Power Supply Unit or LV PSU and the AC Mains. It is also the fault status

screen for the power supplies. A fault would cause one of the listed faults to be

highlighted red for fault or yellow for a warning condition.

System Faults:

• AC Low - triggers if the AC input to the MOV board goes below 177Vac

• AC High - triggers if the AC input to the MOV board is above 264Vac

• MOV Fuse 1, 2 or 3 - turns yellow if one or more of the MOV protection

fuses on the MOV board is open.

LV PSU Faults are generated by the Vicor power supply unit and monitored by the PS

Monitor board. The dc voltage faults are triggered at +/-15% of nominal.

Figure 3-16 Power Supply Screen

The PAPS (Power Amplifier Power Supply) icon will turn red or yellow if any of the

faults on this screen are activated. Figure 3-16 shows the possible icon configurations

with red being critical faults and yellow simply a warning condition.

3.8.1 PS Service

This is an on-line help screen telling how to remove a power supply, but also allows for

calibration of the AC Mains reading on the Power supply screen in Figure 3-16.

! CAUTION:

ALWAYS SHUT THE BREAKER OFF ON THE FRONT OF THE PA POWER

SUPPLY BEFORE REMOVING TO PREVENT DAMAGE TO CONTACTS AND/

OR THE POWER SUPPLY.

3.8.1.1 AC Mains Meter Calibration

The AC Mains calibration must be done during transmitter installation, but will most

likely not require adjustment again unless the MOV or PS Monitor board is changed.

This is a critical transmitter adjustment as this reading is used for the AC high and AC

low faults.

Figure 3-17 PS Service Screen

NOTE:

This calibration should always be done with the transmitter shut off. This adjust-

ment can cause various power supply faults to appear momentarily, but can be

safely ignored. If the transmitter is turned ON, these faults can cause the transmit-

ter to mute momentarily.

This section contains information on how to remove and replace electrical and

mechanical parts and any alignments or adjustments associated with the replacement.

All routine alignment procedures are contained in Section 3 with the associated GUI

screen.

5.2 PA Module Removal

The PA module(s) simply push in or pull out of the transmitter. There are no latches or

screws. There is a module off switch located behind the front cover at the top and

bottom of the module so that when the module is grasped to be pulled out, the touch

switch shuts it off first.

5.2.1 CZ1000F PA Module Air Block

For the CZ1000F, a special Air Block (a long, thin Lexan shield shown in Figure 5-1)

has been provided in case one of the modules is to be removed for an extended period of

time. The Air Block simulates the back pressure of a module. This keeps the airflow

through the rest of the transmitter at normal levels even with the module removed. The

Air Block will only fit in Slot #2 (the right-hand slot). Therefore, if a module is to be

removed for a period of more than a few hours, the Air Block should be installed in slot

2 and the remaining module must be placed in slot 1 (if not already there).

To install the Air Block, place the right side into the slot as shown in Figure 5-2. To

finish, squeeze near the back until it starts into the slot on the left. Now using either

your hands or a screwdriver, work it into the slot from back to front. It could also be

installed starting at the front and working your way to the back, whichever works best

for you. When finished, both sides of the Air Block should be captive under the shelf.

NOTE:

If you use a tool to aid installation, be very careful not to bend the aluminum

guide to the left of the slot.

5.2.2 PA Module Pallet Replacement

The phase and gain of the individual pallet amplifiers in the PA Module are tightly

controlled in manufacturing allowing field replacement of the individual pallets using a

"PA Pallet Replacement Kit". The PA Modules are designed to cover a specific

frequency range or BAND within the UHF DTV spectrum. The PA Modules for each

band have a different part number and so do the Pallet Replacement Kits. See Table 5-1.

The tools required for the replacement include:

•Safety glasses

•Soldering iron

•Sn63Pb37 solder (Harris Part# 086-0004-054)

•Alcohol and a piece of cotton cloth

•Medium size Phillips blade screwdriver

•Medium size flat blade screwdriver

•7/64" size Allen wrench with torque indicating mechanism (15 inch pounds)

The Pallet replacement procedure is as described below:

! WARNING:

THE DIAMOND PA MODULES ARE DESIGNED TO HANDLE VERY HIGH TEMPERA-

TURES AND MAY BE EXTREMELY HOT, UP TO 90O F (50O C) ABOVE ROOM TEM-

PERATURE. DO NOT TOUCH THE MODULES WITH BARE HANDS AFTER THE

TRANSMITTER HAS BEEN RUNNING, ESPECIALLY IN HIGH AMBIENT TEMPERA-

TURE ENVIRONMENTS. SPECIAL GLOVES HAVE BEEN PROVIDED IN THE REAR

OF THE CONTROL CABINET OR CAN BE OBTAINED FROM HARRIS, PART #099-

0006-483 OR GRAINGER ITEM #4JF36.

STEP 1 Using the protective gloves, remove the PA module from the

Transmitter.

STEP 2 Place the module on the bench with the lid up.

STEP 4 Unsolder the brown DC power wire from the bad pallet, and stretch it up.

NOTE:

Be sure to properly identify the failed pallet prior to removal. Figure 5-3 can be

used to verify pallet location. The pallets are numbered 1 through 6 with pallet

number 1 being closest to the front of the module.

STEP 5 Unsolder the input and output ribbon wires from the pallet side leaving

them attached on the combiner and splitter. Carefully bend them up and

out of the way. Remove the 7 Allen head mounting screws holding the

pallet in place.

STEP 6 Carefully lift up the pallet using the copper clamps, situated over the RF

Transistors as handles.

NOTE:

Lifting the pallet can be made easier by using a flat blade screwdriver to gently

pry upward on the edge of one of the screws still mounted to the pallet being

removed. Use an adjacent screw on an adjacent board to pry against lifting up on

the board that is being removed. Once the board is loosened in this way the cop-

per clamps can be used to finish removal of the board with less pressure

required.

STEP 7 Remove the thermal pad from the heat sink and discard. These pads

should not be reused.

STEP 8 Wipe off any thermal grease or other residue from the heat sink using the

cotton cloth and alcohol. Make sure the surface is completely clean in

preparation for the installation of the new pallet.

STEP 9 Install the new thermal pad. The pad is oriented so the brown wire is

passed through the hole as the pad is installed on top of the heat sink. It

does not matter which side of the thermal pad is up and which side is

down as there is no performance difference.

STEP 10 Position the new PA pallet in place with the brown wire directed through

the corresponding hole in the pallet.

STEP 11 After the pallet is placed, make sure the DC power wire passing

underneath the pallet is entirely inside of the designated channel in the

heat sink and is not between the pallet and the heat sink.

STEP 12 Install the seven mounting screws and torque each to 15 inch pounds.

STEP 13 Solder the brown DC power wire onto the newly installed pallet using

the soldering iron and Sn63Pb37 solder.

STEP 14 Use an Ohmmeter to check the resistance from the brown power wire

pad to ground. It should be 1K ohm or greater. If the meter shows a short

circuit or low Ohm reading between these two points, remove the pallet,

and check the wire position underneath the pallet. Fix the position of the

wire and re-mount the pallet.

STEP 15 Solder the input and output ribbon wires to the pallet, make sure the

ribbon wire is not broken, damaged, or touching ground at any point.

STEP 16 Clean all three solder connections with a piece of cotton cloth and

alcohol.

STEP 17 Replace the lid on the module and reinstall all the screws.

Install the module back into the transmitter and push the ON button, check the value of

the DC current consumed by the new pallet. It should be the same as for the rest of the

pallets +/- 10%.

5.3 Power Supply Module Replacement

Removal and replacement of the power supply module is a simple matter of shutting off

the breaker on the front of the module, removing the 2 black screws in the front panel

and pulling the module out.

Before replacing the module with a new one be sure to check the AC voltage strapping

on the front side of the supply (inside the aluminum chassis). The power supply

modules can be strapped for 240 or 480 Vac but all Ranger supplies should be strapped

for 240 Vac operation. Proper strapping for 240Vac is shown in Figure 5-4, along with a

picture of the inside of the actual supply chassis. This information (and 480Vac

strapping) is also shown on the Power Supply Wiring Diagram, 843-5494-353 in the

schematic package.

5.4 Circulator Removal/Replacement

The circulators are mounted on an adjustable plate behind the PA modules. It is very

important that when they are replaced that they are mounted correctly or the module

may not seat properly in the circulator. If mounted too far forward, the circulator could

actually hold the module out so that it does not seat properly in the lower module

connector which carries PS, signal and control causing the module not to operate or

become intermittent.

STEP 1 Shut the transmitter off along with the breaker on the power supply.

STEP 2 Pull the PA modules out a few inches to disengage them from the rear

connectors.

STEP 3 Mark the adjustable plate shown in Figure 5-5 for front to back position

(F) on the top as shown and on the bottom. This will make re-assembly

much easier and increase confidence that it is back in the correct

position.

STEP 4 Remove the RF output cables (D) and the reject cables from the

circulators. If necessary, mark them for proper installation later.

STEP 5 Remove the adjustable plate screws (C) and pull circulator assembly

straight back. This should provide access to the screws on the side of

either circulator. The heatsink screws pass all the way through the

heatsink and should only be removed if better access to the circulator

screws is required.

Section 5 Replacement Procedures

STEP 6 The circulator screws are hex head and require an allen tool to remove.

These screws are shown in Figure 5-6.

Figure 5-6 Circulator Side View

STEP 7 Clean the old thermal compound off of the heatsink with cotton cloth

and alcohol. Put a thin layer of thermal compound on the new circulator

and mount it to the heatsink.

STEP 8 Push the modules back into place. Have someone hold the modules

firmly in place or tape them to the cabinet for the next step.

STEP 9 Re-install the adjustable plate with the circulators mounted on it. With

the modules held in place, seat the circulators into the module. The

marks you made earlier should be very close to lining up. They should

not be any further away from the module than before. The most

important thing is that you are not holding the module away from the

lower connector but are making good RF contact to the circulator.

STEP 10 Tighten the screws (C) in the adjustable plate and then re-connect the RF

output and reject cables to the circulators. Make sure you connect the

cables to the same circulator as before.

NOTE:

Swapping the output cables will cause all of the power to end up in the combiner

reject load, while swapping the reject cables will cause the attenuator readings to

be reversed on the GUI and therefore protect the wrong attenuator.

It should not be necessary but you may want to check module phasing and adjust if

necessary for the CZ1000F, see "3.7.2 Module Phasing Procedure" on page 3-18.

6.1 Introduction

This section provides step by step procedures for updating the software loaded onto

each of the controllers in the Ranger transmitter via the In-System Programming feature

or ISP. This allows for software updates without having to change firmware ICs. The

ISP program and the software files for each of the controllers is supplied on the CD-

ROM which came with the transmitter, along with an acrobat version of the technical

manual. The ISP program requires an external Windows PC with an available RS-232

serial port which can be connected to the Main Controller board. This single connection

(via ISP bridging) will allow updating of all controllers, including:

• Main Controller Bd

• PS Monitor Bd

• RF Monitor Bd

• External I/O Bd

NOTE:

The PA Modules require a different serial connection point and therefore have a

separate ISP procedure than the 4 controllers mentioned above.

Section 6 ISP (In-System Programming)

6.2 Installing the ISP Program

The In-System Programming (ISP) application, HarrisISP.exe, is a Windows based

software program. The main requirements are a Windows based PC and an open COM

port.

To install the HarrisISP.exe program simply double click the Setup.exe program located

on the CD-ROM in the directory D:\Firmware\Isp\ as shown in Figure 6-1 or use the

RUN command in the START menu.

Figure 6-1 CD-ROM ISP Directory

Simply follow the on screen instructions and do not change the paths where

the program wants to be installed. When finished you should have the Harris

ISP icon on your desktop, like the one to the right.

6.3 ISP Procedures

The ISP procedure is basically the same for all of the control boards (Main Controller,

RF monitor, PS monitor and External I/O) but is slightly different for the PA Module

controller. The main differences are the serial connection point and the baud rate. This

means there are 2 ISP procedures:

When firmware in the transmitter is updated, all firmware revisions (for the controllers

and the modules) should be checked and brought up to the revision levels on the CD-

ROM if not already the same. The .s19 file names for the controllers and the modules

have the revision number as part of the name.

For example: RANGER_CTRL_APP_0013.s19 is revision 1.3 Main Controller code.

NOTE:

There is a separate ISP procedure used to update the Apex exciter. See the Apex

exciter manual for details on updating Apex exciter software.

6.3.1 Control System ISP Procedure

The example given here is for updating the Main Controller board since the steps are

the same for the other control boards except for the update file. This means the

procedure is to be repeated for updating each of the following control boards:

• Main Controller

• RF Monitor

• PA Monitor

• External I/O

STEP 1 Insert the CD-ROM into the disk drive.

STEP 2 Open the transmitter controller front door. Connect a standard RS-232

cable from the serial port on your computer to DB9 connector J90 on the

This procedure is only for updating the software in the PA Module(s). The

HarrisISP.exe program must have already been installed on your computer.

IMPORTANT:

This procedure is intended for use on the CZ500F and CZ1000F modules only.

STEP 1 Insert the CD-ROM into the disk drive.

STEP 2 Open the transmitter back door. Connect a standard RS-232 cable from

the serial port on your computer to the DB9 serial connector on the

Backplane Interface board. See Figure 2-1 on page 2-2 for physical

board location.

STEP 3 Run the “Harris ISP.exe” program. The window shown in Figure 6-9

should open.

STEP 4 Set “Port” to the number of the COM port being used on your computer.

STEP 5 Set “Baud” to 9600.

STEP 6 Press Query Micros; wait for system to recognize the 1 or 2 PA Module

micros as shown in Figure 6-10. The micros are at address 33 and 34 so

it will take a minute for them to show up. Note the status indicator at the

bottom left corner of the window. If it does not find the micros, press

Stop Query, change the COM port and press Query Micros again.
